Wouldn't Stadium be different without the transfer pak? I mean you could still play those mini-games the same, but I remember the default Pokemon you got really sucked if you didn't use a transfer pak with your own game.
I only played through Snap once but I did like it. I barely remember it but for some reason remember feeling like I didn't get everything out of it that I wanted to, like I left a lot of stuff to be unlocked or something.

I'm still holding out on the rumble for the controller. That middle button on the top of the controller looks like it's meant to hold something to the back of the controller and I'm just thinking it's gotta be a rumble pak or something. It could be something to hold the remote so you have to use the controller AND motion sensing together but shut up cuz I want it to be for the rumble.

I'm sure they'll be on the VC sooner or later.
Perferably sooner.
I loved Pokemon Stadium but it is a huge game. There is a lot you can do in that game. So I'd think there is a lot of code which may take a while to adapt onto the VC.
